Steps in Magnet Stirring

The magnetic stirring plate uses a revolving magnet to create an area of low pressure, which generates a continuous liquid flow. This liquid will follow the lines of magnetic force, creating a vortex inside the flask. The liquid is evenly distributed throughout, and surfaces are agitated to provide better heat transfer.

The main steps in using a magnetic stirrer area are listed below.

Create a Vortex in the Magnetic Stirrer Bar

Place your sample on top of the central magnet with some liquid buffer solution, such as distilled water, in the flask to start stirring. The central magnet will fix itself to your stirrer bar using a viscous attraction force. The external magnets will revolve around the central magnet, creating a vortex inside the flask and stirring. Distribute the fluid in the flask as rotating speeds increase. Eddies are formed that distribute the molecules in the liquid.

Stir With Slowing Speed to Incubate Your Sample

You may want to incubate a boiling point at a lower temperature during the stirring process. This can be done by reducing the magnetic stirring process speed so that the fluid follows and stays around the vortex longer. As a result, absorbs more heat from its surroundings, and the boiling point can be reached at a lower temperature.

Collect Samples From the Test Tubes

If you want to collect a reaction sample, switch off and remove the power supply. Wait until the central magnet is rested before opening your flask. Typically, magnetic stirrers are used in laboratories because they can be safer than alternative stirring methods.

The magnetic stirrer plate can be used for analytical purposes, such as measuring pH or studying chemical reactions. The speed at which the vortices appear can be adjusted for different applications, and the intensity of the plates is adjustable. It requires no moving parts or bulky power supplies, so it can be carried around easily, making it ideal for fieldwork.
